" Vim syntax file
" Language:	automake Makefile.am
" Maintainer:   Debian VIM Maintainers <[email protected]>

" XXX This file is in need of a new maintainer, Debian VIM Maintainers maintain
"     it only because patches have been submitted for it by Debian users and the
"     former maintainer was MIA (Missing In Action), taking over its
"     maintenance was thus the only way to include those patches.
"     If you care about this file, and have time to maintain it please do so!
"
" This script adds support for automake's Makefile.am format. It highlights
" Makefile variables significant to automake as well as highlighting
" autoconf-style @variable@ substitutions . Subsitutions are marked as errors
" when they are used in an inappropriate place, such as in defining
" EXTRA_SOURCES.
